2. Mix oil, vinegar, soy sauce and spices in a small bowl or measuring cup. Put kale in a roasting tray, pour the mixture over kale, and mix well (with hands is easiest). Ensure kale is spread out evenly in a single layer, use another pan if there is too much.

3. Bake for 10 minutes, check crispiness, and bake for 5-10 minutes more if required. Sprinkle over the salt just before serving.
